Research On Land Sparing Versus Sharing Strategies For Targeted Poverty Alleviation Service Of Guangxi

Land poverty alleviation is an important tool for poverty alleviation in China.Scientific and reasonable land strategies should be selected and formulated to facilitate the development of targeted poverty alleviation." land sparing versus sharing " from the perspective of ecosystem services,and to explore the theory framework of land use strategy,under the guidance of the theoretical basis for the research of land policy for poverty alleviation,effective will be crucial for poverty alleviation,ecological protection,material production and the concept of sustainable land use comprehensive consideration,the role of coordination in the relationship,promoting the construction of ecological civilization and poverty alleviation work accurately.This paper takes Guangxi Zhuang Autonomous Region as the research object,selects 2015 as the research time,takes county as the research unit,targeted at targeted poverty alleviation services,carried out a study on land sparing versus sharing strategies.Firstly,the land sparing and sharing strategies of counties in Guangxi were selected based on the factors of land intensification degree,ecosystem service value,agricultural landscape structure and rural social and economic development.Furthermore,the spatial differentiation characteristics of poverty in different strategy zones are analyzed and poverty trap areas are identified.On the basis of the above research,selecting the poverty-causing index,using the method of geographical detector and regression analysis,detecting the main poverty-causing factors and the interaction relationship between the factors,and analyzing the spatial differentiation pattern of the poverty-causing factors.Therefore,it puts forward the optimization measures of targeted poverty alleviation,identifies the types of poverty-stricken rural areas,and proposes the appropriate poverty alleviation mode.Therefore,it puts forward the optimization measures of targeted poverty alleviation,identifies the types of poverty-stricken rural areas,and proposes the appropriate poverty alleviation mode.The research results provide references for the targeted poverty alleviation work in Guangxi.The main conclusions are as follows:(1)The spatial differentiation pattern of land intensification degree in Guangxi is high in the southeast and low in the northwest.Ecosystem service value and farmland habitat heterogeneity generally present a "concave" spatial differentiation pattern with high surrounding area and low central area.The spatial differentiation pattern of rural social and economic development is the gradient pattern of the north low and the south high.The 55 counties are divided into land sparing areas,which are economically and industrially developed areas and ecologically fragile areas.Scientific planning is adopted to reasonably divide land use ef1 ficiency areas and natural state conservation areas.The 55 counties are designated as land sharing areas.These areas are mountainous areas with higher terrain and primary industry as the leading industry.We should give full play to the function of improving the environmental quality of farmland and improving ecological supply and service,and establish a friendly way of using biodiversity and land.The regional division of land use strategies provides the basis for the exploration of differentiated targeted poverty alleviation services.(2)Most of the poverty trap areas in Guangxi are in the land sharing areas,mainly distributed in the area adjacent to Yunnan-Guizhou plateau in the northwest of Guangxi,which is a concentrated area of karst landform and rocky desertification.Therefore,it is required that targeted poverty alleviation services should be inclined to the trap areas.Most of the cold spots of poverty occur in the land sparing areas,which are mainly cities with developed industries,tourism and logistics as well as capital cities.Industrial development and urban functional positioning play a positive role in alleviating regional poverty.Targeted poverty alleviation services should stimulate the externality of urban economic development in poverty-stricken cold spots and promote the overall development of regional economy.(3)The impact of poverty causing factors on poverty varies greatly in the land sparing areas.Regional development degree,distance of main roads,average slope,average altitude,development level of secondary and tertiary industries are the poverty causing factors that have a great impact on poverty.The impact of poverty factors on poverty in the land sharing areas varies little,with the regional development level,the level of compulsory education,the distance to railway,the total value of the ecosystem and the distance to main roads being the major factors.(4)Geographically weighted regression analysis is more suitable for the investigation of the impact of poverty-causing factors in Guangxi.The average altitude and the development level of the second and third industries in the land sparing areas,the total value of the ecosystem and the regional development degree in the land sharing areas are the poverty factors with spatial heterogeneity effect on the impact of poverty.According to the spatial effect,the counties affected by the average altitude were divided into the natural condition restriction type,taking the sparing land remediation and allocation model.Counties greatly affected by the development level of the second and third industries are designated as industrial development leading type,taking the sparing industries to help alleviate poverty model.The counties affected by the above two factors are divided into natural conditions and industrial development double factor influence type,taking sparing land remediation allocation and industrial poverty alleviation comprehensive model.Counties affected by the total value of the ecosystem were classified as ecologically sensitive type,taking sharing ecological compensation poverty alleviation model.Counties greatly affected by regional development were defined as socio-economic constraints type,taking sharing Comprehensive facility construction model.Counties affected by the above two factors are divided into ecological environment and social economy influence type,taking sharing Ecological compensation and establishment of comprehensive poverty alleviation model.
